combiSpot is a wireless detector, which contains a seismic sensor and two magnetic sensors. The seismic sensor reacts to vibrations and it is possible to adjust the sensitivity of the seismic sensor on the central unit. The two magnetic sensors are activated by means of an external magnet within a short distance. The unit is supplied with an internal battery. combiSpot contains two magnetic sensors, but one of them has only a sabotage function meaning that if both magnetic sensors are activated at the same time a malfunction will be registered. It is possible to use both the seismic sensor and one of the magnetic sensors at the same time. The central unit program will indicate if the seismic sensor or/and the magnetic sensor must be used.
